This would give you a resonant match which could be hard on the xmfr under
some conditions.  It's better to calculate resonant match as you did, and
then use the equation:

C = 1.6 * Cres

This will give you a slightly larger value and works good because there will
not be a large resonant rise because the xmfr and cap.

If running a synchro gap, then use C = 3.2 * Cres

At this power level you would use two static gaps in series with a max
setting (total of both) at or less than 0.160 - 0.180 inches.
